Abstract

The utility model discloses a concrete rod vertical pole device, which comprises a tripod holding pole and a power mechanism arranged on the tripod holding pole. The fixed pulley is connected with the movable pulley arranged on the concrete pole. The main pole of the "tripod" is refitted with a tripod pole machine, which does not require a tractor to grind into the construction site, which greatly reduces the area of ruined greenery, not only saves a large part of funds, but also speeds up the construction. The work efficiency is greatly improved, and the work intensity is greatly reduced; in addition, the reverse switch control is adopted to ensure safety. The utility model has the advantages of simple structure, low material consumption, greatly saved time and reduced construction cost.

Description

Concrete pole device

technical field

The invention belongs to the technical field of concrete pole vertical pole equipment for electric power engineering construction, and in particular relates to a concrete pole vertical pole device.

Background technique

In common concrete poles and poles, "herringbone" shaped poles and twisted poles are used. Among them, 4 people are needed to operate the winch, 4 people are needed to grind the ground drill, 4 people are needed to control the "herringbone"-shaped pole holding legs, and at least 3 people are needed to pull the wind rope after the concrete pole leaves the ground at an angle of about 60°. The assembly of the pulley block requires 2 people, and at least 17 people are required to work together for each concrete pole. If a 10-meter or 12-meter concrete pole is lifted, it takes at least 30 minutes under normal circumstances, and the safety factor is low and the risk is high. In addition, a safe distance of at least 13 meters should be kept between the tractor winch and the "herringbone"-shaped pole, which directly leads to the large compensation area, the head of the household does not agree to the construction, and the construction resistance is too large. The phenomenon of construction stoppage occurred, which caused the unit to double the construction cost, resulting in the inability to complete the construction task according to the original plan, seriously affecting the construction period, and increasing the time for shutdown and power transmission.

Utility model content

The utility model provides a concrete pole pole device which does not need to be ground by a tractor, reduces the ruined area of the field, saves manpower, and improves the efficiency of the pole.

A concrete rod vertical pole device, comprising a tripod holding pole and a power mechanism arranged on the tripod holding pole, the power mechanism is connected with a fixed pulley set at the top of the tripod holding pole through a steel wire rope, and the steel wire rope is connected to the fixed pulley through the fixed pulley. The movable pulley connection on the concrete pole.

The power mechanism includes a motor arranged on the pole of the tripod, the motor is connected with a two-speed twisting mill through a chain, the two-speed twisting mill is connected with a steel wire rope, and a lift switch is set on the motor.

The utility model utilizes the main holding pole of the "triangular frame" to modify the tripod vertical pole machine, and does not need to be grinded by a tractor to enter the construction site, which greatly reduces the area of ruined greenery, and has won the understanding and support of the head of the household, not only saving a large part of funds , and speed up the construction. The tripod pole machine currently used only needs 4 people to look at the legs of the pole, 3 people to look at the pole wind rope, and only 2 people to transfer the generator. A total of 9 people can quickly complete the operation task. Each concrete pole uses the improved lifting equipment, which only takes about 15 minutes (not including the transfer time), which greatly improves the work efficiency and greatly reduces the work intensity; in addition, it adopts reverse switch control. In the case of power failure, the motor automatically activates the locking device, which can effectively prevent the pole from sliding down and endanger personal safety, greatly reducing the risk factor. This equipment has been demonstrated through repeated experiments and has been used in normal construction, and has been well received by front-line construction workers. unanimous praise. The utility model has the advantages of simple structure, low material consumption, greatly saved time and reduced construction cost.

Description of drawings:

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the structural representation of the utility model.

Detailed ways

As shown in Figure 1, a kind of concrete rod vertical pole device, comprises tripod holding pole 1 and the power mechanism that is arranged on the tripod holding pole 1, and described power mechanism is arranged on the top end of tripod holding pole 1 through steel wire rope 2. The pulley 3 is connected, and the steel wire rope 2 is connected with the movable pulley 5 arranged on the concrete pole 4 through the fixed pulley 3 .

The power mechanism includes a motor 6 arranged on the tripod pole 1, the motor 6 is connected with a two-speed twisting mill 8 through a chain 7, the two-speed twisting mill 8 is connected with the wire rope 2, and the motor 6 is Set lift switch 9. A single-phase 1.6KW motor is installed on the pole 1 of the tripod, and the speed is 2900 revolutions per minute. According to the safety factor of the lifting equipment, a deceleration device is installed to make the motor reach 60 revolutions per minute. The lifting tonnage is 1.2 tons, and it is equipped with single-phase gasoline. Generator (2.9KVA) 1 set. According to the basic principle of the reducer, the main shaft has 7 teeth, the second shaft has 83 teeth, the third shaft has 7 teeth, and the fourth shaft has 54 teeth through theoretical calculations to ensure the motor 2900 rpm, and through continuous experiments, an additional 60μF capacitor is installed , so that the motor reaches a constant speed of 60 rpm.
